Bleeding may occur if the gauze is pulled hard on the second day of a stab wound. On the second day of a stab wound, the wound is unlikely to be completely healed, and the wound is likely to continue to ooze, which will form a bloody scab that will stick to the gauze. In this case, if the gauze is tugged on, it will cause the scabs to tear off, and this will lead to bleeding of the wound. The proper treatment for this situation is to wet the gauze covering the wound site with iodophor and leave it for a few minutes to separate the gauze from the scab, then carefully remove the gauze. Finally, disinfect the wound again with iodophor and remove the dirt from the wound surface. Wait for the wound to dry slightly before covering it with a new gauze or wound dressing. In addition, during the healing process, it is recommended that the patient go to the hospital and have the wound cleaned and changed by a doctor. In addition to cleaning the wound, it is also necessary to observe the wound wound healing recovery. Actively adjust the medication program to ensure the smooth recovery of the wound wound.
